I currently use an aimtech saddle mount on my 870 20 gauge, and it is solid, but sits high since you can see the bead under the saddle mount. For those of you that have used the sun optics saddle mount, can you see the bead under this mount or is it contoured to the receiver tightly?? Just wondering as it may help some with some sights running out of adjustment for being too tall on the aimtech style saddle?
